The phrase "are derived by combining" is correct and usable in written English.
It can be used when explaining how certain results or outcomes are obtained through the process of combining different elements or components.
Example: "The final results are derived by combining various data sets to ensure accuracy and comprehensiveness."
Alternatives: "are obtained through the combination of" or "result from the merging of".
First, some conditions to guarantee the FTS and the FTB for a class of fractional order LTI systems are derived by combining a new property for Caputo fractional derivatives, the generalized Gronwall inequality and the Laplace transform.
The kinetostatic synthesis equations are derived by combining the kinematic synthesis and static equilibrium equations.
The Weibull distribution parameters involved in the damage model are derived by combining the geometric conditions obtained from the conventional triaxial compression tests.
Dynamic governing equations are derived by combining the 5-dof maglev vehicle model, the modal properties of guideway structures and a LQG controller for electromagnetic suspension.
This paper aims at determining, for various boundary conditions, the optimal operating fan frequency and the corresponding back pressure of a typical large-scale air-cooled coal-fired power plant via accurate off-design models of both the turbine subsystem and air-cooling condenser, which are derived by combining aggregated physical equations and real operating data.
Patterns are derived by combining data from different tables of the Hydrological Atlas [51].
An on-line, semi-explicit control algorithm is derived by combining these two techniques.
Further detail can be derived by combining neighbouring intersections that enclose or partially enclose individual blocks.
Global quality ratings (poor, fair, or good) were derived by combining scores from each subscale.
